I've had psoriasis since I was nine years old. It flares up with stress. I get injections (it really just pricks the skin a bit) of Kenalog right into the site. It usually lasts 3 months but this past one has lasted 6.

Also, be careful if anyone is on Lithium. It can aggravate psoriasis and make it worse.
